SPECIFICATION forming part of Letters Patent No. 450,974, dated April21, 1891.

Application filed December 15,1890. Serial No. 874,717. No model.)

To all whom, it may concern.-

Be it known that I, HENRY O. NYE, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in Boiler-Cleaners,of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

The purpose of this invention is to eliminate the mineral substancesfrom the feedwater entering the boiler and thus prevent incrustation ofthe latter; and to that end the invention consists, essentially, of oneor more pans situated in the upper part of the interior of the boiler,and the feed-water pipe having its discharge end in one end of said panor pans, as hereinafter more fully described, and specifically set forthin the claim.

In the annexed drawings, Figure 1 is a side View of a boiler providedwith my invention, a portion of the boiler-shell being broken away toshow the devices for eliminating the extraneous mineral substances fromthe feedwater. Fig. 2 is a transverse section on line 0: m, Fig. 1. Fig.3 is a detached vertical longitudinal section of the pans, withthefeedwater pipe and blow-off pipe attached thereto,

and Fig. 4 is an enlarged longitudinal section illustrating theoperation of the apparatus.

Similar letters of reference indicate corresponding parts.

B represents the boiler, and c c the flues through which the products ofcombustion pass.

P and P represent two open-topped pans,

which are arranged end to end in one continuous plane and communicatewith each other at their junction. Said pans are situated in the upperpart or steam-space of the boiler and extend lengthwise thereof.

In new boilers suitable supports for the pans may be applied to theboiler-shell, but for supporting the pans in boilers already in use Iprefer to employ suitable metallic posts or trestle t 15, mounted on thetop row of lines o c, and carrying upon their tops the aforesaid pans,as illustrated in Figs. 1 and 2 of the drawings. I incline the panstoward one end of the boiler and build across the interior of the pansat or near their junction a dam b, which extends part way the height ofthe pan,

and provided at the exterior thereof with the blow-off cock (I.

The pan P constitutes a steam-trap, which water-seals the discharge endof the feedpipe, so as to prevent back-pressure of steam in said pipe.The other pan P constitutes the precipitate collector, and the operationof said pans is as follows: In feeding water to the boiler whilegenerating steam, the-water issuing from the feed-pipe agitates thewater in the pan P, as represented in Fig. l of the drawings, andthereby prevents the impurities from precipitating in said pan. Neitheris the infiowing water retained in said pan a sufficient length of timeto heat said water to the temperature which separates the impuriblownout of the pans and through the blowoff pipe a by the pressure of thesteam in the boiler.

I do not limit myself to any particular nu mber of pans to be used in aboiler, inasmuch as that depends on the length of the boiler, but inevery case the pans are to be connected end to end and inclined towardone end of the boiler, as shown. It is also obvious that in a boiler ofordinary length a single pan may be made of sufficient length to an- Thepans swer the purpose of myinvention.

are introduced into the boiler through the manhole thereof and areeasily set upon their supports inside of the boiler and coupled togetherend to end. The form of the supports of the pans depends somewhat on thestyle of boiler to which the pans are to be applied.

Having described my invention,what I claim as new, and desire to secureby Letters Patent, is

The combination, with the boiler, of the precipitate-collecting, pan Pand the steam-trap pan P, both open at the top, connected to-
